• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang xa hoi. ((hieu ve) OR (hieu van)) cham soc va danh vai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang xa hoi. ((hieu ve) or (hieu van)) cham soc va danh vai ((cua tre) OR (cua te))*".
